This SAE Aerospace Recommended Practice (ARP) defines the documentation, environmental considerations, test and evaluation criteria necessary to support certification of additive manufactured parts used on aircraft seats and associated furnishings. This document is to be used in conjunction with the existing applicable regulatory documents and requirements for parts which are used in low-criticality and non-critical applications.

This SAE Aerospace Recommended Practice (ARP) defines acceptable methods for determining the effect of disinfectants application to passenger and crew seating products in transport aircraft. This ARP selected a standard application process for all disinfectants in order to remove one variable from the investigation, which, at the time, was more concerned with the unknown effect of disinfectant chemicals on seat materials. The SAE Aircraft Seat Committee noted that most disinfectant manufacturers have their own application regimens to ensure the effectiveness of their product and that these differ from those defined in the ARP. Consequently, the standard application methodology defined in the ARP is not suitable for qualifying disinfectants, but is rather a standard method to compare the disinfectant’s behavior across a range of seat materials. Acceptance of individual disinfectants for specific application regimens is outside the scope of this ARP.

This document applies to webbing used on occupant restraint systems in service on 14 CFR/CS part 23, part 25, part 27, and part 29 aircraft applications. The guidelines presented within this document are intended to be supplemental to the requirements supplied by the OEM in the CMM, ICA, or like document. In cases of conflict between this ARP and the OEM’s requirements, the requirements of the OEM shall be followed. The objective of this document is to establish practical guidelines to help operators in the determining if restraint webbing has reached the end of its service life. The recommendations contained herein are based on test data from in service restraint systems and the continued airworthiness guidelines recommended by restraint system OEMs.

Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for other crew members, including cabin attendants. The recommendations herein include coverage of such items as harness reels, shoulder harnesses, and safety belts. However, the intention is not to limit the design of restraint devices to these particular system components only. These recommendations apply primarily to forward-facing seats. However, the design must take into account the fact that loads may be applied from any direction and be of a magnitude at least as great as those specified in current FAR's.

Part I of this document relates to the restraint systems for the flight deck crew. Part II considers restraint systems for flight attendants and other crew members. As applicable, the same criteria should be incorporated in both Part I and Part II installations. The recommendations herein include coverage of such items as harness reels, shoulder harnesses, and safety belts. However, the intention is not to limit the design of restraint devices to these particular system components only. These recommendations apply primarily to forward-facing and aft-facing seats. However, the design should take into account the fact that loads may be applied from any direction and be of a magnitude at least as great as those specified in current FAR's.

This document outlines the evaluation and documentation appropriate when the components of an approved aircraft seat restraint system are replaced or modified by a party other than the Original Equipment Manufacturer of the restraint system.

This document provides informational background, rationale and a technical case to allow consideration of the removal of the magnesium alloy restriction in aircraft seat construction as contained in AS8049B. The foundation of this argument is flammability characterization work performed by the FAA at the William J. Hughes Technical Center (FAATC), Fire Safety Branch in Atlantic City, New Jersey, USA. The rationale and detailed testing results are presented along with flammability reports that have concluded that the use of specific types of magnesium alloys in aircraft seat construction does not increase the hazard level potential in the passenger cabin in a post-crash fire scenario. Further, the FAA has developed a lab scale test method, reference DOT/FAA/TC-13/52, to be used as a certification test, or method of compliance (MOC) to allow acceptability of the use of magnesium in the governing TSO-C127 and TSO-C39C.

This document is a guide to the application of magnesium alloys to aircraft interior components including but not limited to aircraft seats. It provides background information on magnesium, its alloys and readily available forms such as extrusions and plate. It also contains guidelines for “enabling technologies” for the application of magnesium to engineering solutions including: machining, joining, forming, cutting, surface treatment, flammability issues, and designing from aluminum to magnesium.

Seat furnishings are installed around seats and are intended to enhance passenger privacy and comfort. They may have provisions for additional occupants to be seated when the aircraft is in-flight, but would not be occupied during taxi, take-off, and landing (TTL). This Aerospace Standard (AS) establishes the minimum design, performance and qualification requirements for seat furnishings with and without upper attachments (see Figures 1 and 2) to be installed in large transport category airplanes. This standard excludes seat furnishing designs that are directly attached to the seat assembly, for which AS8049 is the applicable standard. Integrated items (desk tops, cabinets, shelves, stowage areas, closeouts, dividers, etc.) connected to seat furnishings shall comply with the requirements of this AS as part of the seat furnishings.

• AIRBAG COMPONENT MINIMUM PERFORMANCE REQUIREMENTS • AIRBAG INSTALLATION PERFORMANCE REQUIREMENT Current revision will only contain Part 25 and lapbelt installed airbags. Future revisions will expand to include Structural airbags, 3-point restraint airbag, pre-tensioner etc.

This Aerospace Recommended Practice (ARP) defines acceptable methods for determining the seat reference point (SRP), and the documentation requirements for that determination, for passenger and crew seats in Transport Aircraft, Civil Rotorcraft, and General Aviation Aircraft.

This SAE Aerospace Recommended Practice (ARP) defines a means of assessing the credibility of computer models of aircraft seating systems used to simulate dynamic impact conditions set forth in Title 14, Code of Federal Regulations (14 CFR) Parts 23.562, 25.562, 27.562, and 29.562. The ARP is applicable to lumped mass and detailed finite element seat models. This includes specifications and performance criteria for aviation specific virtual anthropomorphic test devices (v-ATDs). This document provides a recommended methodology to evaluate the degree of correlation between a seat model and dynamic impact tests. This ARP also provides best practices for testing and modeling designed to support the implementation of analytical models of aircraft seat systems.

This SAE Aerospace Recommended Practice (ARP) defines means to assess the effect of changes to seat back mounted IFE monitors on blunt trauma to the head and post-impact sharp edges. The assessment methods described may be used for evaluation of changes to seat back monitor delethalization (blunt trauma and post-test sharp edges) and head injury criterion (HIC) attributes (refer to ARP6448 Appendix A Items 3 and 6, respectively). Application is focused on type A-T (transport airplane) certified seat installations.

This document provides background information, rationale, and data (both physical testing and computer simulations) used in defining the component test methods and similarity criteria described in SAE Aerospace Recommended Practice (ARP) 6330. ARP6330 defines multiple test methods uses to assess the effect of seat back mounted IFE monitor changes on blunt trauma to the head and post-impact sharp edge generation. The data generated is based on seat and IFE components installed on type A-T (transport airplane) certified aircraft. While not within the scope of ARP6330, generated test data for the possible future development of surrogate target evaluation methods is also included.

This SAE Aerospace Standard (AS) defines minimum performance standards, qualification requirements, and minimum documentation requirements for passenger and crew seats in civil rotorcraft, transport aircraft, and general aviation aircraft. The goal is to achieve comfort, durability, and occupant protection under normal operational loads and to define test and evaluation criteria to demonstrate occupant protection when a seat/occupant/restraint system is subjected to statically applied ultimate loads and to dynamic impact test conditions set forth in Title 14, Code of Federal Regulations (14 CFR) parts 23, 25, 27, or 29 (as applicable to the seat type, see Table 1). Guidance for test procedures, measurements, equipment, and interpretation of results is also presented to promote uniform techniques and to achieve acceptable data. While this document addresses system performance, responsibility for the seating system is divided between the seat supplier and the installation applicant.
